Broken Permalinks and breadcrumbs

Hi

I noticed a problem with the breadcrumbs when creating new knowledgabse article. In the space where the breadcrumbs should be we see this error.

Home Kb Warning: Invalid argument supplied for foreach() in /var/sites/i/<website-removed>.co.uk/public_html/wp-content/plugins/wp-knowledgebase/wp-knowledgebase.php on line 508

Line 508 is
<?php
foreach($kbe_bc_term as $kbe_tax_term){
?>

So as a workaround I disabled the breadcrumbs in the settings. This removed the error by removing the breadcrumbs, but changing the setting also broke the permalink to the knowledgebase articles This happens when I turn the breadcrumbs on or off.

I’m running this particular website in a test environment and also a live environment with the same results.

Can I report this as a potential bug please?

Thanks, Julian
